I have studied both Chinese and Spanish. Though not fluent, I'm confident that I can get the correct pronunciations. I am solid with accents.
I have numerous audiobooks under my belt, including both fiction and nonfiction, many of which are on Audible. I have experience working with ACX and can guarantee that my files will be accepted with no trouble.
My per finished hour rate is $450. Your book will be about 10 hours long, bringing your total to $4,500. If you would like some post production work, like music and atmospheric SFX added in, I can do that, too, for an extra $50 per finished hour.
I hope to hear from you soon.
